Nguyen HT, Nguyen TD, Le TML, Trinh QP. Integrative taxonomy of Mesocriconema onoense (Tylenchida: Criconematidae) from Vietnam highly suggests the synonymization of Mesocriconema brevistylus and related species.

Abstract
The genus Mesocriconema is one of the most diverse genera within the family Criconematidae, known as ring nematodes, with more than 90 species. Although species in this genus usually show distinct morphological characterizations, the identification based only on morphology can lead to misidentification in many studies resulted in a number of synonymizations in the genus over time. In this study, an integrated approach has been applied in characterizing Mesocriconema onoense from Vietnam. The molecular data of 28S rRNA, ITS, 18S rRNA regions were analyzed and discussed to confirm the correct names on GenBank. Besides, phylogenetic analyses of 28S rRNA, ITS, and 18S rRNA regions of Mesocriconema species revealed that Mesocriconema brevistylus should be considered as a junior synonym of M. onoense. Consequently, M. helicus, M. onostris, and M. paronostris should also be considered as the synonyms of M. onoense.
